This invention relates to new and useful improvements in incinerators.

One object of the invention is to provide in an incinerator separate compartments of novel arrangement whereby different kinds of garbage and trash can be burned at the same time.

Another object of the invention is to provide fines or openings in the partitionssepa- 0 rating said compartments. These fines or openings are to be arranged in mismatched relation and located at the top, bottom or sides of these partitions so that regardless of how full each compartment is with burning 5 material, suitable flues and proper draft will be provided. p

Still another object of the invention is to provide sloping floors in each compartment having grates located therein, so that the gar- 5 huge will more readily feed to said grates or may be raked thereon and also wh reby ashes can be raked more easily into the grates.

A further object of the invention is to provide an auxiliary combustion chamber having a grate adjacent the outlet duct of the burning chamber next to' same whereby an intense fire may be maintained for burning and melting cans and other material difiicult to consume.

A still further object of the invention is to provide means whereby it is necessary for the gases and air currents escaping from the combustion chamber to pass through the grate of the last burning section to the smoke stack,

so as to prevent burning material being drawn into the stack.

A construction designed to carry out the invention will be hereinafter described, to gether with other features of the invention.

. The invention will be more readily understood from a reading of the following specification and by reference to the accompanying.

In the drawings the numeral 10 designates the front wall, 11 the back"wvall,12 the right v side wall and 13 the'left sidewall of the main burning or combustion chamber of the iii-F5517: cinerator. Within thechamber is an elevated E 7 floor 1 1 in which center grates--15 preferably a of the rocker type, are set substantially flush. The burning chamber has an arch 17 spanning Q from the front to the back wall. An air space 18 is provided abovethefarch under a floor19. Charging hoppers 20 mounted in the floor 1 9 '1. extend through the arch so as to discharge 1 onto the grates. closure 21. y y r r 1 7 The floor 1 1, as. is shown in Figs. 2, 3 and 8 is downwardly inclined from ther'ear' wall; Y 11to' the grates 15 andis alsodownwardly 5' inclined from the front wall 10"to the said grates. This gives a slight hopper effect to .39 1" the floor so that refuse piled, on the floor will 7 tend to work toward the grates. Also-the refuse or ashes therefrom may be readily raked onto the grates.

..Each hopper has asuitable 7 I i The burning chamber is divided into seci tions or compartments A, B, C and Dby upright partition walls 16. Viewing Figs. 1 and 4, the section A is at the extreme right hand side of the structure, while the section D is at the extreme left hand side thereof.

An. important feature of the "invention resides in the draft openings in the partition walls 16. The section D (Fig. 3) has connection through its ash pit 31with a transwith. a smoke stack 33. The products of combustion, such as gases and air currents, mustpass from, onesection to another to-' ward the section D and escape fromthe latter .Verse horizontal flue or duct 32 connected through the duct 82. If. the refuse piledin a 10o ing gases might-result in considerable dam age. In order to overcome these difliculties draft openings are located in the various partitions,as is shown in Figs. 2, 8 and 8.

In the partition between the sections A and B an opening 16 (Figure 3) is located at the 19 top of said partition, While an opening 1%. is located at the bottom thereof and these openings are offset laterally from each'other. In the partition between the sections B and C (Figure 8) a top openingl60 is'provided in 1;, offset relation to the bottom opening 16?). All the partition openings are offset laterally from each other so that the gases and currents will-take a circuitous path and also so that-at'least one opening will at all times be is ,open. a This arrangement not only assures a draft but provides a'better circulation. An enlarged discharge opening connects the section C-with the section D, thus assuring a free escape of the gases and currents into i the section D.

Fire doors 22 are provided in the front wall for the various sections and underthese door-s ash doors 23 are arranged for raking The 80-,p1t 31', which is under the section D.'1s someout the ashes fromthe pits 24 and 31.

what longer than the other pits and extends back to the entrance to the flue features are illustrated in my Letters Patent No. 1,570,531 issued January 19, 1926, and 35.:need-notbe' described herein.

In operating the incinerator a fireis built on the grate 15 in the section A, but it could be-bu'ilt in either the section'B or the, section C if'the preceding section was not to be 2used. The fire is started in any suitable manner with any. suitable fuel. Garbage and refuse is dumped from the =floor 19 through -the charging hoppers, which being located directly over the grates 15 in the sections A, B andC will cause said-garbage and refuse to be dumped onto said grates. However, the garbage and refusewillbverflow the grates, but as the mass is consumed the inclined floor 16 will tend to cause the garbage and refuse to work down onto the grates.

Of course the matter to be burned may be more readily raked onto the grates owing to 'the inclined floor. The ashes can also be easily pushed onto the grates and discharged int-0 the pits below. 7

The other Various changes in the size and shape of the different parts, as well as modifications and alterations, may be made within the scope of the appended claims.

What 'I claim,-is:
